| Short description | Semi-evergreen vine thicket on serpentinite |
| Structure code | Low Closed Forest |
| Description | Semi-evergreen vine thicket on serpentinite. Species include Brachychiton rupestris, Gossia bidwillii, Notelaea longifolia, Cupaniopsis wadsworthii, Diospyros spp., Croton insularis, Alyxia ruscifolia, Turraea pubescens, Samadera bidwillii and includes the endemic Neoroepera buxifolia. Occurs on narrow hillcrests, upper slopes, gullies, footslopes and lateritised hills with shallow to moderately deep stony red to brown clay loams and clays formed from moderately weathered or lateritised serpentinite hills and mountains. Not a Wetland. (BVG1M: 7a). |

| Special values | 11.11.21: Habitat for threatened flora species including Samadera bidwillii and Neoroepera buxifolia. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction burning in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Exotic grasses, such as Guinea grass and Buffel grass, can fuel fires that carry into and damage vine thickets. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Herbicide control of exotic grasses, or short term grazing, on the edge of vine thickets will reduce the risk of wildfires damaging vine thickets. |
| Comments | 11.11.21: A rare ecosystem that occurs in the Marlborough Plains subregion. Some areas have been cleared for mining. |
